PAPER-FASTENING DEVICE.

Specification of Letters Patent.

Application filed March 29, L912. Serial No. 685,093.

The primary object of our invention is theprovision of means whereby aplurality of lamped together by means of a tongue st l. from the paperitself, and without the use of clips. rivets eyelets or like devices.

A further object of the invention is to provide means whereby aplurality of tongues struck from a plurality of sheets of paper may beforced through a slit cutin said sheets and thus the sheets tied Afurther object of-the inn tion is to provide a mechanism in the forn'iof a hand stamp between which sheets of paper may he placed, and whichupon a depression of the stamp will cause the tongues r to be struck outfrom the paper and in sorted through a slit made in the paper.

A. further object of the invention is to provide a very simple,effective and easily operated mechanism to this end adapted at oneoperation to form the attaching tongues, slit the paper and insert thetongues in said slit.

Further objects of the invention will ap pear in the course of thefollowing description.

Our invention is illustrated in the accompa nyi ng drawings wherein:

end of the base 2 eierred to taken as the blade rises and draws thetongues through the slit made in. the paper. Fig. 7 is a face view of asheet of paper showing the manner in which the attaching tongue passesthrough the paper. Fig. 8 is a. sectional view on the line 88 of Fig. 7.Fig. 9 is a perspective view of the tongue-cutting punch. Fig. 10 is asectional Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the accompanying drawingsby the same reference characters.

Referring to these drawings it will be seen that 2 designates a hollowbase which houses a portion. of the mechanism and which is provided witha flat upper portion designated 3. This upper portion is longitudinallyslotted as at at, one end of the wall be ing formed with a relativelyenlarged socket 5 and the other end of the slot intersectingtransversely extending slot 6. The rear is provided with the laterallyspaced upstanding ears 7 between which is pivoted the arm 8 by rheans ofthe transversely extending pivot pin 9. The arm 8 normally extendsupward at its free end and is held in this position by means of a spring8 one end of which is support;- ed in the socket 5 while the other endis supported in a socket 10 formed in the arrn near the base thereof.The forward 'end of the arm 8 carries upon it the transverselyextending: head 11 from which projects the upwardly extending knob 12formed with it flattened upper end adapted to be struck by the hand ofthe operator.

Carried upon the under side of the head ll is th downwardly extendingpunch 13 which :1:- shown in Fig. 10 is approximately rectangular incross section but tapers toward its rear end. It will likewise'be seenfrom Fig. i that the face of the punch 13 is inclined from its forwardedge to its rear edge so that upon adepression of the punch, the rearedge 14 will commence to cut sooner than the front edge will. This punch13 isfor the purpose of cutting out the tapering tongue as will behereafter de scribed.

Mounted upon the forward face ofthe head 11 is the downwardly extendingslitcutting blade 15, which extends below the punch 13. This bladeasshown in Fig/la tapers from its upper end to its lower end.

I above the plate 17 in spaced and is provided adjacent its lowerextremity with the eye 16. This eye is as wide as the. broadest portionof the punch 1.3, and it wil be seen from Fig. Pillitit the upper Well0; the eye 16 is approximately level. with the forwerd ed e let of themuch 13. Su

b ported upon the face 3 of the base 9. unniediotely above thetransversely extending slot 6 is a. plate 1? formed with :1 rearwardlyextending slot 18, this slot tapering rezir- Wurdly, and the rear end ofthe slot in register with the rear edge of the punch 13 when. said punchis depressed so thatlhe slot 18 forms part of a cutting die, of whichthe punch is the other member. Disposed relation there to is a plate 19formed with longitudinal slot 20 and with a transversely extending slit21. permit the passage through it of the punch 13, While the slit 21 issufficiently large to permit the blade 15 to pass thercthrough.Preferably the plate 17 supported upon the base by means of screws 23,while the plate 19 is spaced from the plate 17 by nticuns of a spacingblock and is held thereto by means of a screw 25.

' While we do not wish to liniit ourselves to any special means forsupporting tne punch 13 upon the head 11, we huVe clown for this purposethe punch 13 us being formed with a base flange notched ut oppositepoints in its diameter as at 26, and through which pass the screws 527which enter a plate 28 supported in any suitable manner upon the underside of the head ii. By this means the punch may be removed wheneverdesired for regrind ng or for repair, It will be seen also that theblade 15 supported upon the head. by means oil it screw 29, and that byremoving this screw the blade may be removed, regrcund, replaced oradjusted. W

Mounted upon the under face of the plate 17 are the downwardly extendingspaced cars 30. These have ii iproxiinutely lTilQ SfLl'llC length as thewidth of the transverse slot 6 and extend rearward so as to form tongueguides us will be later explained.

Projecting from the interior face of the front wall 2 of the base 2 isthe bifurcated supporting stud 31, and pivoted within this stud is thelinger the upper end of whi h outwurdlv and upwurdl; curved as andnorn'ially disposed imu'iediutel v hcncu. the under face ol the plate1]". It will seen that the finger 3-; has a relatively lore andrelatively narrow extremity whi h is adapted in the operution ol' thedevice to once through the eye ll on the blade The linger 232?. isprovided Willi a rcurwurdly and upwardly projcctiw tail 34;, end piwoted upon the linger for lice upwurd move- Iuont llut normally reelingupon this lull a bi'l'urcuten extension 35 whirl. is no i'nieliy Theslot is sutliciently large to- 62, inch is depending from the base oneach side of the rear end of slot 4. This hell crank 36 line {aforwuriflly proje ting uriu 39 which extends forward and nornuill isupported somewhat fil'lli ll) oi the hell crunlt extends upward throughthe slot l and then is hurlined lorwurd and upward so to have engagementwith the under face of the arm l. Preterziblv the upper end of the arml0 is twisted so to lie llut against the under face of the arm 8 andhuve u rubbing contact therewith. A spring ell. acts to hold the arm 10into engagenient with the arm 8. The spring 8 of course acts lo hold thearm 8 in its upperni permits the 05L position and therefore spring ll-lto hold the arm 40 in its upperinoet posi ion with the arm 39restingabove the extension l For the purpose of holding the ling-er 32in its raised position. we prov de :1 spring 42 which as illuslruled isa C(lll sprincz, the middle porl ion of which passes throug l the lingerand the lateral ends of which sire at lueheil in any suitable manner tothe lateral walls of the forward part oil the base portion. i l c donot, however, wish to be limited uurliculzir form ol spring" is it isobvious that :1. number of other 'loi'ms might be used which would.accomplish the some purpose.

In the operation of our invention, several. sheets of paper which aretached to each other are placed between the plate and 1!), the uuirgiuuledges oi? lhe sheets striking i'igzi'iust the spacing member 2. The head11 is then forced dmvnword ziguiuel'. the force oi the spring 8. As thehead ill i'uoves downward, the blade 15 punctures u. slit designated ain the paper A throu h lhe several uhcets, and {if-i the punch movedownward it cuts out :1 tongue designuied Z). will be seen that the rearedge i l of the punch l3 will first etrilic the paper ;iu l lluit asilie punch deer-(unis, the tongue will. be cutout. liuisniuch as thesides of the tongue I) are cut out l'icl'orc the front edge ll of thepunch reaches: the paper, it will be obvious that the further descent ofthe punch will not cut the tongue eni'irolv from the paper but willHlillplfv' act to force these tongues into the slot 18. As the headmoves ilowi'iwui'd, the arm 8 will push downward upon the arm 4-0 of thebell crank 3(1 The loiwi'ui'tl end 35) of the hell crank will bedepressed. and utriltiun' against the extension if will. druw dowmvurdupon the lziil of the linger 3:2 drawing the pointed of actuating thelinger ore the extension 39 The otherextremity 33 of the finger rearwardand downward to the position shown in Fi l and behind the tongues. Whenthe punch is nearly fully depressed or in the position shown in. the toue Z2 will have been cutout forced nward between the guide flanges 30and the eyeloi the blade 15 will be below the plate 17. ()n a slightfurther depression of the head 11, the end of the arm 39 of the bellcrank 36 will slip by the extension and release the finger, whereuponthe spring 1-2 will cause the finger to move forward, projecting the endof the tongue or tongues 6 through the eye 16. Upon the upward movementof the head 11, the blade 15 will move upward and carry the extremitiesof the tongues I) upward through the slit (1 so that these tongues willthen be in the position shown in Fig. 6. As the paper is drawn out frombetween the plates 17 and 19, the plate 19 will cause the extremities ofthe tongues to be folded fiat against the paper, and the several pliesof paper will be securely held together by the refolded interengagingtongues without the use of eyelets, clamps, clips or any lihe devices.

It will be seen that it is necessary that the finger 32 be formed withthe pivoted extension 35 as otherwise the arm 39 ofthebell crank 36could not pass this finger upon an upward movement of the arm 39 andtherefore could not return to a position above the extension 35.

Inasmuch as the tongues Z; are struck out from several folds of paperand pass through several folds of paper, it will be plain that theengagement between the seve'al sheets of paper will be relativelystrong, permitting a few of the sheets being detached from each other,without damage to the sheets, when desired.

iVhile we nave described the operation as taking place in successivesteps, it will be understood that as a matter of fact, the clampingtogether of the papers is practically accomplished at one actuation ofthe machine. The paper is placed in position between the plates 17 and19 and the head depressed by a blow. The formation of the tongue and thethreading of the tongue into the blade or needle 15 and the drawing ofthe tongues through the slit (1- are all accomplished at one stroke\Vhat we claim is:
